As a durable material with toughness, elasticity, and high strength, rubber is used in a wide range of applications such as automotive tires, construction machinery, aerospace, and mechanical parts, such as seals, tires, conveyor belts, tracks, connectors, etc. The wear resistance and heat dissipation properties of rubber directly determine the service life of rubber products. If the wear resistance decreases, rubber products will lose quickly in working conditions and even affect their use; if the heat dissipation performance decreases, it will accelerate the aging of rubber, thus reducing the strength and wear resistance. Therefore, the comprehensive modification of wear resistance and heat dissipation of rubber wear-resistant masterbatches from China factory is extremely important to enhance the service life of products and adaptability to the operating environment.


SI-69 (SI-50) rubber wear-resistant masterbatches from China factory can significantly improve the wear resistance strength, permanent deformation, fixed extension strength and tear strength of rubber products, and the Mooney viscosity of rubber materials in the mixing process is significantly reduced, and the sulfur change performance is improved.
